title: Oxygen in bulk monocrystalline diamonds and its correlations with nitrogen.
abstract: The distribution of oxygen and nitrogen impurities in diamond single crystals from a variety of origins and qualities was investigated using secondary ion mass spectrometry. A positive correlation between these impurities is observed over a wide concentration range. It is suggested that in diamonds oxygen is present not only in submicroscopic inclusions, but also as a lattice impurity. It appears that the presence of oxygen in a given crystal volume suppresses the IR-activity of nitrogen defects.
